Hmm ... easy to see that no tried, tested, true solution exists, eh, ladies?
I've ordered one of those manual tally counters. Had to go to bloody eBay, in the end. How I loathe eBay. Anyway, the bastard I ordered it from is supposed to've sent it overnight delivery; but to say that I have my doubts is grossly understating the case.
So I shall shortly (depending) be able to add my comments re yet another method of counting rows.
